Origin of meteoritic stardust unveiled by a revised proton-capture rate of O
M. Lugaro, A. I. Karakas, C. G. Bruno +34
Stardust grains recovered from meteorites provide high-precision snapshots of the isotopic composition of the stellar environment in which they formed. Attributing their origin to…
Ne and Na ejecta from intermediate-mass stars: The impact of the new LUNA rate for Ne(p,)Na
A. Slemer, P. Marigo, D. Piatti +36
We investigate the impact of the new LUNA rate for the nuclear reaction NeNa on the chemical ejecta of intermediate-mass stars, with particular focus on the ther…
The impact of the revised ON reaction rate on O stellar abundances and yields
O. Straniero, C. G. Bruno, M. Aliotta +33
Context. Material processed by the CNO cycle in stellar interiors is enriched in 17O. When mixing processes from the stellar surface reach these layers, as occurs when stars become…
Impact of a revised Mg(p,)Al reaction rate on the operation of the Mg-Al cycle
O. Straniero, G. Imbriani, F. Strieder +28
Proton captures on Mg isotopes play an important role in the Mg-Al cycle active in stellar H-burning regions. In particular, low-energy nuclear resonances in the Mg(p,)$^…
First Direct Measurement of the ^{17}O(p,γ)^{18}F Reaction Cross-Section at Gamow Energies for Classical Novae
D. A. Scott, A. Caciolli, A. DiLeva +29
Classical novae are important contributors to the abundances of key isotopes, such as the radioactive ^{18}F, whose observation by satellite missions could provide constraints on n…
Revision of the 15N(p,γ)16O reaction rate and oxygen abundance in H-burning zones
A. Caciolli, C. Mazzocchi, V. Capogrosso +27
The NO cycle takes place in the deepest layer of a H-burning core or shell, when the temperature exceeds T {\simeq} 30 {\cdot} 106 K. The O depletion observed in some globular clus…
